The only thing I know about Cochise is that it filed Chap 11 back in 1982.
Air Resorts has had an interesting history. At times it had both domestic scheduled and flag carrier status (for Mexico service). The company received its scheduled certificate in 1982 but stopped scheduled flights in 1985 and lost the scheduled certificate in 1987. Air Resorts then operated charter only service from 1985 to 1989. It then began scheduled charter service before reapplying for a scheduled certificate. That was granted in 1989. They then operated twice-daily SAN-TUS in the Convairs, starting in May 1990 but ended service after only 8 months, mainly due to rising fuel costs during the last Gulf crisis and a fare war between WN and AWA.
They reapplied to the FAA in 1992 and were once again determined fit to operate as a scheduled commuter with plans to operate LAS-Grand Canyon service.
Air Resorts over the years operated a variety of routes including Burbank, San Diego, Carlsbad, Baja California, Tucson. At one point around 1995, 49% of the company was owned by David Walsh (I don't remember the majority owners name). Walsh bought into Air Resorts and was planning to use it to start an airline called PSA. Walsh also tried to purchase Fresno-based Air21 just prior to Air21 ceasing operations. I'm not sure if he is still connected with Air Resorts.
